CBERS-4 Wide Field Camera Multispectral Satellite Imagery

Multispectral imagery is captured by the CBERS-4 satellite's Wide Field Imaging Camera. The sensor provides data in four spectral bands (blue, green, red, near-infrared) with a 64-meter spatial resolution and an 866-kilometer swath width. The imagery is provided by the CEOS_EXTRA organization via NASA's Earthdata platform.

Use Cases

• Large-scale land cover classification using the four spectral bands (B, G, R, NIR).
• Monitoring vegetation health and agricultural patterns via the near-infrared (0.77-0.89µm) band.
• Assessing water bodies and coastal areas using the blue (0.45-0.52µm) and green (0.52-0.59µm) bands.
• Supporting rapid revisit monitoring activities leveraging the sensor's less-than-five-day revisit capability.

Strengths

• Four distinct spectral bands for multispectral analysis.
• Wide 866-kilometer swath width enables large-area coverage.
• High temporal revisit frequency of less than five days for monitoring.

Limitations

• Spatial resolution of 64 meters is coarse for detailed object detection.
• Specific row count, file size, and temporal coverage are unknown.
• Data quality may be affected by atmospheric conditions and sensor calibration.
